실험 절차

The sodium aluminosilicate of Example 44 was prepared as follows. Approximately 300 L of hot process water and 12.4 kg of anhydrous sodium sulfate were added to a 1200-L reactor. While mixing, the reactor contents were heated to 55° C., and 5.9 L of sodium silicate were added to the reactor and mixed. A 25-min simultaneous addition step with alum and silicate solution followed, using a sodium silicate addition rate of 19.9 L/min and an alum addition rate of 7.26 L/min. After the simultaneous addition step, a reduced alum flow rate (1-2 L/min) was used to bring the batch pH to about 5.3. After digesting the batch for 10 min, the product slurry was washed and filtered using a press filter. The filtered cake was collected. A portion of filtered cake was spray dried and hammer milled to an average 5-6 micron particle size.
